Example: Bought used car from individual a few months back with strange smell. After last heavy downpour, realized water was leaking in. Pulled back fabric on seat to discover lots of black mold in seat foam/ cushion.

What are the symptoms of mold exposure and how long between exposure to onset of symptoms? I’m trying to determine if my headache, skin & sinus irritations are due to the mold exposure or pregnancy symptoms (as pregnancy can bring about all those irritations).

Any resources greatly appreciated. Thanks!
